Dental infections is an academic concept and research field dedicated to understanding the microbial etiology, pathogenesis, clinical manifestations, treatment, and prevention of infections originating in the oral cavity and associated craniofacial structures. This area encompasses the study of diverse conditions such as dental caries, pulpitis, periodontitis, and odontogenic abscesses, investigating their complex polymicrobial nature, mechanisms of local tissue destruction, potential for systemic spread, and crucial significance for both oral and general systemic health.
